Simulation of speed control of a stepper motor using phase locked loop

how to control the speed of the stepper motor using phase locked loop

[C.J. Harris]

Through closed loop control? I don't know - you haven't really given much information.

[ibrahim]

yeah closed loop i.e. phase locked loop

[C.J. Harris]

Are you are doing velocity feedback via some type of data acquisition card? Or is this all simulation?

[ibrahim]

nah, is all simulation in simulink

Answer 1

There are plenty of tutorials for this already, just look for those related to velocity feedback control:

If you don't need the derivative control (in order to improve damping) just set the appropriate gain to zero.

thanks for ur help so far, but i am not controlling velocity, i am controlling the speed of a stepper motor using PLL. i have managed to get the model of the PLL but the problem now is how to include the stepper motor and stepper motor driver into the model in order to control the speed for simulation.
